Good To Know

Q: Are these lines exact replacements for the OEM ones? A: They are manufactured to match the original routing and dimensions, but slight differences in material composition may exist; verify your model's vin for full confirmation.

Q: What is included in the 'deluxe' version? A: The deluxe kit typically includes extra washers, O-rings, or fasteners that are often reused or lost during a standard line replacement, helping you complete the job without trips to the store.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
